I just learned it's time to do a rebuild on the Tieck Aire 1/2 hp double head compressor. So, just how hard or time consuming is it? Anyone here have experience? I have two that run in tandem for the 6 diffuser Kasco system. Can a dummy like me actually rebuild? I have found out that when I attempt such things, I usually have to forward the unit, along with parts or missing parts to the people that know what they are doing and that usually raises the price, where if I just shipped it out in the first place it would already be back repaired. Where if I do it , it might not ever be repaired. Do they make a book or youtube a rebuild for dummies? Thoughts
